HEATED WATER HOSE FOB FILLING- STATIONS Application filed April 1, 1029. Serial No. 351,791.

This invention relates to means for electrically heating a hose so that liquids or the like passing through the hose will be heated, the general object of the invention beinlgto embed an electric heating coil in the wal s of the hose and connect the ends of the same to a source of supply so that the current passing through the coil will heat the hose and the liquid passing through the same.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

' In describing the invention in detail reference will be had to the accompanying rawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing part of a hose constructed in accordance with this invention and showing the thermostatic means thereon for controlling the circuit.

Figure 2 is a view partly in section, showing the invention.

As shown in these views, the hose 1 has embedded in its walls an electric heating coil 2 which extends substantiall the length of the hose, with the positive an negative wires connected together at one end of the coil,

- the wires being separated and insulated from each other by the walls of the hose which is of rubber or the like. One end of one wire is connected to a terminal 3 in a casing 4 suitably fastened to a part'of the hose and the end of the other wire is connected to a thermostatic strip 5, as shown at 6. The free end of this strip normally contacts a terminal 7 carried ,by the casing.

Thus current will flow from one terminal through the two parts of the coil to the strip and other terminal, but if the heat generated reaches a certain degree, the strip will bend and thus break contact with the other terminal and then the circuit will be broken,

From the foregoin it will be seen that the liquid or other flui s passing through the hose will be heated by the heat generated by the coil.

This hose can be slip (1 over a pipe to prevent the liquid in the pipe from freezing and if desired, instead of making the device in the shape of a hose, it may be made flat so that it can be wrapped around a pipe or the like and suitably fastened in place to prevent freezing of the liquid in the pipe or other member around which the device is wrapped.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A fluid heater comprising a hose, an electrical heating coilembedded in the hose, walls formed on the hose to provide a socket, an insulated casing mounted in the socket, a shoulder in the casin a terminal post carried by the casing an connected to one end of the coil, a second terminal post carried by the casing and located adjacentthe shoulder, and a thermostat member having one end secured to the casing and the'pther end of the coil and extending across the shoulder into engagement with the second} mentioned terminal post to complete a circuit and influenced by the heat of the coil to break the circuit when the fluid in the hdse has been heated to a desired temperature/ In testimony whereof I aflix my signature.

CARL RAYMOND MATHEWS.

but as soon as the device cools, the circuit will be closed a ain, as the strip will return to its first position and contact the terminal.
